Abstract
Description
- The present invention relates to a cladding assembly and method, e.g. for tiling a roof.
- In a conventional method for cladding a pitched roof, an array of longitudinally extending parallel battens is mounted to the roof, the spacing of the battens corresponding to the intended spacing of the tiles. Tiles are then laid on the battens, and secured in place. This securement is generally effected by nailing, several nails being required for each tile. Plainly this is time-consuming. It brings a risk of introducing points of leakage, particularly as the roof weathers. A tile is secured only at a few locations. The result may be unsightly.
- The present invention makes possible a rapid cladding method in which it is unnecessary to apply nails or other securing means to the exterior of the tiles. Thus, cladding elements (such as tiles) and supports may be mutually adapted to allow snap-engagement. A cladding element is provided with a pair of oppositely facing hook formations at opposite edges, and the support means provide tongues for engaging a pair of different hook formations provided by an adjacent pair of cladding elements. The tongues are provided by retaining profiles which may be connected to supports such as conventional battens. Each profile is adapted to support an adjacent cladding element. Each profile extends for at least a substantial part of the width of a cladding element, and may extend across a plurality of cladding elements, e.g. across an entire roof or other clad surface. Thus a cladding element can be supported for substantially its whole extent. The tongues and/or hook formations should have some resilience to facilitate engagement. Preferably the arrangement is such that one hook formation of a cladding element can be offered up to hook behind a tongue when the element is projecting away from its cladding configuration; after engagement, the element can then be moved to its cladding configuration, with its other hook formation finally engaging the tongue of an adjacent support means. This support means may already be engaging the tongue of opposite type of the adjacent cladding element.
- A preferred form of retaining profile has a formation for engaging a batten or other support; a tongue; and a support flange for extending in the cladding direction beneath the tongue, so as to provide support for an end region of a cladding element whose hook portion is engaged with the tongue.
- In another aspect of the invention provides a method of cladding a surface by providing supports having tongues and cladding elements having hook portions, and mutually engaging them generally as indicated above.
- In another aspect the invention provides a kit of parts for cladding a surface, including such hooked cladding elements, and support means which provide tongues, and which may comprise retaining profiles.
- Some embodiments of the invention will now be described in greater detail with reference to the accompanying drawings in which:
- Fig. 1 is a plan view of a tile;
- Fig. 2 is a front elevation of the tile;
- Figs. 3,4 and 5 are sections on lines A-A, B-B and C-C respectively in Fig. 1;
- Figs. 6 and 7 are details in plan and front elevation of a modified tile;
- Fig. 8 is an end elevation of a tile retaining profile supporting a tile;
- Fig. 9 is a schematic section through a portion of a roof incorporating tiles and profiles as shown in the preceding figures; and
- Figs. 10 and 11 are views similar to Figs. 1 and 2 but showing a modified embodiment.
- The
tile 10 shown in Figs. 1 to 5 is generally rectangular in plan, having long front andrear edges region 16 adjacent the front edge from whichridges 18 run rearwardly towards therear edge 14. Between theridges 18 there aresmaller ridges 20 extending forwardly from therear edge 14. At one lateral side (the right as seen in Fig. 1) there is alow overlap area 22 with a plurality ofsmall ridges 24. At the other lateral edge there is acomplementary portion 26 which provides a socket in which the right-hand portion 22 of an adjacent tile is engageable. - At the rear edge there is an
upstanding flange 28. As can be seen from the sectional views of Figs. 3 to 5, this provides an upwardlyopen hook formation 30 at the rear of the tile, whereas the raisedregion 16 at the front provides a downwardlyopen hook portion 32. This has a front edge delimited by a flange whereof anupper portion 34 extends downwardly and forwardly, and afinal portion 36 extends downwardly and rearwardly. - Such a tile may conveniently be formed of a resin/glass composite material. This can easily be produced by conventional resin injection techniques, using inexpensive plant.
- Figs. 6 and 7 show end regions of a tile 10ʹ generally similar to the
tile 10 of the preceding figures, but having a series ofgrooves 33 running from front to rear, so as to provide downward projections. The grooves are also indicated in broken lines, in Figs. 3 and 8. - Fig. 8 shows a
tile retaining profile 40. This is a plastics extrusion which has to be fairly tough but with some resilience. A suitable material has been found to be a semi-rigid ABS, 1mm thick. The profile presents a rear batten-engaging formation 42, in this example provided by a pair ofwall portions flange 46 which terminates with afree end 47 some way above the bottom end of thewall 45. Thewall 45 has a forwardly extendingflange 48, which extends beneath theend 47 of theflange 46. Atile 10 is shown, supported by theflange 48 which extends for its whole width. The tilesrear flange 28 is hooked under thetongue 46. If the tiles has grooves orribs 33, these tend to deform the profile, and cause therear flange 28 of the tile 10ʹ to be urged up behind thetongue 46. It can be seen that the leading edges of the ribs are angled to assist engagement. - Fig. 9 shows a portion of a roof which slopes downwardly from right to left, and bears horizontally extending
wooden battens 50. These are of rectangular section, and each bears atitle retaining profile 40, being embraced by thewalls profiles 40 are secured to thebattens 50, e.g. being nailed through, so that thetongues 46 project from the lower sides of the battens. Once theprofiles 40 have been attached, thetiles 10 can be mounted. Starting at a lower edge region, therear hook formation 30 of a tile is hooked under theangled flange 46 of a profile, with the tile initially held approximately at right-angles to theflange 46, and then laid down as shown. The next higher tile can then be applied, by engaging itsupper hook formation 30 in the next highest batten'sprofile 40, and laying it down by pivoting anti-clockwise until it abuts thelower batten 50, and itsfront hook formation 32 snap-engages behind theflange 46 of itsprofile 40. Of course, the spacing of thebattens 50 must correspond to the lengths of the tiles (though some minor adjustment is possible by the mounting of the profiles 40). In this manner the tiles can be swiftly and efficiently engaged, without the need for any nailing, or indeed any external fixing elements. - If it is desired to remove a tile, use may be made of an implement having a wide blade with an upturned lip with which one can hook the inturned
flange portion 36 of thefront hook 32 of a tile, and pull it free of theprofile 40. - As an example of dimensions, with a tile of width about 370mm (from front to back) and height about 30mm, a
profile 40 may be of ABS which is 1mm thick, with theflange 46 about 18mm long, itsfree end 47 being 10mm from thewall 46 and 7mm from thebottom flange 48. - The
tile 110 shown in Figs. 10 and 11 is in most respects similar to that of Figs. 1 and 2. Its plan is similar, with opposedlong edges overlap region 102 is provided by alarge ridge 18, terminating with a downwardly and outwardly extendingflange 106. Theopposite region 104 resembles a cut-off ridge 18, and can be overlaid by theother region 102 of anadjacent tile 110, with itsend flange 106 sitting in the relatively recesseddrainage channel 108. The tile is also shaped to providedrainage channels 109 suitable for end barge cappings to sit in. - Near the
rear flange 28 and adjacent the overlaidoverlap region 104, there is anupward projection 112. When tiles are being located side by side, they are pushed together so that the overlap regions 102,104 engage. Theprojection 112 makes it very easy to achieve this accurately. Generally, a course of tiles will be laid side by side before the tiles of the next higher course are laid.
